Technical Field

[0001] The utility model relates to the field of elevator inspection and detection, in particular to a multi-angle gap measuring device used for elevator inspection and detection. Background Art

[0002] An elevator is a permanent transportation device that serves several specific floors in a building and whose car runs on at least two rows of rigid tracks that are perpendicular to the horizontal plane or have an inclination angle of less than 15° to the plumb line. In actual use, the gap between the elevator door and the body gradually increases due to issues such as age. In order to ensure the safety of the elevator, the gap of the elevator needs to be inspected regularly, so a gap inspection device is required.

[0003] Most of the current gap inspection devices use tape measures to measure gaps, and there are also some mechanical measuring devices. When it is necessary to measure the widest and narrowest points of the gap in the elevator, it is often necessary to divide a gap into multiple points and measure them one by one, making the existing elevator gap measuring devices more complicated to use.

[0004] In view of the above technical defects, a solution is now proposed. Utility Model Content
